Abstract
A stabilized white-light-emitting OLED device includes an anode, a cathode, a light-emitting layer disposed between the anode and the cathode, and a stabilizing substituted perylene material, so that the lifetime of the white-light-emitting OLED device is increased.
Claims20
A stabilized white-light-emitting OLED device, comprising:
- a) an anode;
- b) a cathode;
- c) a light-emitting layer disposed between the anode and the cathode;
- and
- d) a stabilizing substituted perylene material, so that the lifetime of the white-light-emitting OLED device is increased.
2 more elements
A stabilized white-light-emitting OLED device, comprising:
- a) an anode and a cathode spaced apart from the anode;
- b) a hole-transporting layer disposed over the anode;
- c) a yellow-light-emitting layer and a blue-light-emitting layer disposed between the hole transporting layer and the cathode;
- and
- d) a stabilizing substituted perylene material disposed at least in one of the following layers:
- the hole-transporting layer;
- the blue-light-emitting layer;
- or the yellow-light-emitting layer, so that the lifetime of the white-light-emitting OLED device is increased.

A stabilized white-light-emitting OLED device, comprising:
- a) an anode and a cathode spaced apart from the anode;
- b) a hole-transporting layer disposed over the anode;
- c) a yellow-light-emitting layer and a blue-light-emitting layer disposed between the hole transporting layer and the cathode;
- d) an electron-transporting layer in operative association with the cathode and either the yellow-light-emitting layer or the blue-light-emitting layer;
- and
- e) a stabilizing substituted perylene material disposed at least in one of the following layers:
- the hole-transporting layer, the blue-light-emitting layer, the yellow-light-emitting layer, or the electron-transporting layer, so that the lifetime of the white-light-emitting OLED device is increased.
